Question

Give the difference between active transport and diffusion (significance in plants).

Answer 1

Differences between active transport and diffusion are given below in the table:

Active Transport	Diffusion
It is the process of flow of molecules against the concentration gradient i.e. from their low to high concentration through a semi-permeable membrane.	It is the process of spread of molecules in a medium along the concentration gradient i.e. from their high to low concentration.
It is an energy-consuming process, so need ATPs as an energy source.	It is a passive process and does not need energy.
Significance: Mineral nutrients such as nitrates, potassium, sulfates, and others are actively transported by root hairs in plants.	Significance: Plants use diffusion to exchange gases during respiration and photosynthesis.
